We study interventions to restore efficient lending and investment when financial markets fail because of adverse selection. We solve a design problem where the decision to participate in a program offered by the government can be a signal for private information. We charac terize optimal...

This is a preliminary draft of an Invited Symposium paper for the World Congress of the Econometric Society to be held in Seattle in August 2000. We discuss the strong connections between auction theory and 'standard' economic theory, and argue that auction-theoretic tools and intuitions can...

The most important issues in auction design are the traditional concerns of competition policy-preventing collusive, predatory, and entry deterring behaviour. Ascending and uniform-price auctions are particularly vulnerable to these problems (we discuss radiospectrum and football TV-rights...

This paper provides an elementary, non-technical, survey of auction theory, by introducing and describing some of the critical papers in the subject. The most important of these are reproduced in a companion book, The Economic Theory of Auctions, Paul Klemperer (ed.), Edward Elgar (pub.),...

We consider second-price and first-price auctions in the symmetric independent private values framework. We modify the standard model by the assumption that the bidders have reference-based utility, where the reserve price (minimum bid) plays the role of the reference point. In contrast to the...

The experimental literature has documented that there is overbidding in second-price auctions, regardless of bidders' valuations. In contrast, in first-price auctions there tends to be overbidding for large valuations, but underbidding for small valuations. We show that the experimental evidence...

A buyer seeks to procure a good characterized by its price and its quality from suppliers who have private information about their cost structure (fixed cost + marginal cost of providing quality). We solve for the optimal buying mechanism, i.e. the procedure that maximizes the buyer’s expected...

In the basic adverse selection model, a seller makes a contract offer to a privately informed buyer. A fundamental hypothesis of incentive theory is that the seller may want to offer a menu of contracts to separate the buyer types. In the good state of nature, total surplus is not different from...

A group of rational individuals with common interest need to select one of two outcomes. The optimal decision depends on whether certain premises or pieces of evidence are established as being true, and each member receives a noisy signal of the truth value of the relevant premises. Should the...
